Soil strength in two freshwater marshes after increased nutrient availability: Field nutrient addition experiments from 2009-04-15 to 2018-04-26

Soil shear strength measurements were collected from two isolated freshwater marshes (Joyce Wildlife Management Area, an anchored marsh; Salvador Wildlife Management Area, a floating marsh) over 10 years after nitrogen (N) and phosphorous (P) additions were annually applied to the surface in spring. Porewater data was also measured at both sites.

本数据集采集了两处独立淡水沼泽（乔伊斯野生动物管理区，固着型沼泽（anchored marsh）；萨尔瓦多野生动物管理区，漂浮型沼泽（floating marsh））的土壤抗剪强度（soil shear strength）数据，采集周期为每年春季向两处沼泽地表施加氮（N）、磷（P）后的10年时段。此外，两处研究站点均同步测定了孔隙水（porewater）相关数据。
